So today, dust on the rear! That was quite simple. I first mixed some Summer Kursk Earth and Dust Effects. I think this latter is a bit too bright and may bleach the surface. It's a first application, I'm actually drawing the map for my future effects and I'm preparing the model for pigments.

First I moistened the surfaces with some thinner and applied my mix, quite diluted as well, concentrating on the areas prone to getting dirty: the corners and the bottom. Moistening the surfaces allows me to break the surface tension (thanks Rick), making my effects flow more easily and giving my brush the time to work the colors. Moreover, it makes it possible, after a while, to soften the edges or work the places where it looks awkward.

Then, I felt the urge to paint the driver's cabin... I failed my first attempt, so I started it all... Grey primer, some rust colors, some clear coat and Worn Effect. Then I airbrush my basecoat and started chipping it with different tools (brushes with more or less hard bristles, metalic objects, ...) To give some harmony, I made a quick wash with the basecoat, then added some more chips with a brush or a sponge. Once it was all done, I added some filters and started working with oil nuts that I dragged downward or faded out. Finally, I made a quick and light pinwash.
